Magnetometry survey This geophysical survey was completed using a Sensys FMG650/3 system. Readings were recorded at a resolution of 0.01 nT and data collected with a traverse interval of 1 m and a sample interval of between 0.16 - 0.25 m. 3.1.3 Data was collected by traversing the survey area in 4 m increments using a quadbike-towed nonmagnetic cart system to achieve the best possible results. The survey produced good results throughout and has not revealed any anomalies of confident early archaeological origin. Several linear anomalies were noted across the Site survey data which have been found to correspond to the positions of land division illustrated in historical Ordnance Survey (OS) maps (1830's - 1880's) and (1888 - 1915). A former footpath is also noted in the southern portion of the Field 2 survey data and is also illustrated in historical OS maps (1830's - 1880's). The remaining anomalies are limited to being caused by overhead power lines, a modern service as well as land drains. Ferrous disturbances along the survey extent is also noted caused by peripheral fencing and external objects. Ferrous 'spikes' caused by modern waste, within the subsoil are also noted sporadically throughout the survey data
